About

Professional summary

I am a Lead Fullstack Developer who builds complete products from scratch, from architecture and backend services to frontend applications and production-ready delivery.

I specialize in TypeScript and Node.js ecosystems, with strong experience designing scalable microservices using NestJS, Next.js, React, gRPC, GraphQL, REST APIs, and event-driven systems.

I enjoy solving problems at the intersection of software and hardware. My work includes real-time fleet platforms processing vehicle positions, telemetry, and ultrasonic sensor data through MQTT, WebSockets, and scalable messaging infrastructure.

I have delivered enterprise CRM, fintech lending, identity and SSO, loyalty, parking, e-commerce, booking, and internal business systems. I am comfortable owning platform architecture, solution design, integrations, and end-to-end technical implementation.

I work with relational, time-series, geospatial, and analytical databases, as well as Docker, Linux, CI/CD, observability, and cloud-compatible storage. I also have experience with React Native, locally hosted AI models, route optimization, and 3D development simulators.

I am motivated by technically challenging product work where I can lead development, build reliable systems, and turn complex operational requirements into practical software solutions.
